Apache Ignite Extensions - Modularization Apache Ignite Extensions - Modularization Saikat Maitra Twitter @samaitra Github samaitra Motivation • To keep Apache Ignite core modules and extensions modules to have separate release lifecycles. • Few integrations which are no longer in use can be deprecated. • Help Apache Ignite community to support core and extensions separately (test, release, fix, continue development). 2 Project Structure • Ignite-core • Ignite-modules • Memory-Centric Storage, Native Persistence, RDBMS • Spark Integration Integration (CacheStore for RDBMS) • SpringData and SpringBoot • Key-Value APIs • TensorFlow Integration • SQL Cassandra Integration • Compute Grid • • Service Grid • Machine Learning APIs • Advanced queries -scan, continuous • Transactions • Data Structures and Atomics • Ignite Messaging • Core Streaming APIs such as IgniteDataStreamer • Logging • Metrics & Tracing framework • Command line tools and scripts such as Visor and control.sh • Standard (aka. thick clients) - Java, .Net, C++. • Spring Core - needed for configuration needs. 3 Apache Ignite Extensions • Flink - Ignite Flink Streamer consumes messages from an Apache Flink consumer endpoint and feeds them into an Ignite cache. • Flume - IgniteSink is a Flume sink that extracts events from an associated Flume channel and injects into an Ignite cache. • Twitter - Ignite Twitter Streamer consumes messages from a Twitter Streaming API and inserts them into an Ignite cache. • ZeroMQ - Ignite ZeroMQ Streamer consumes messages from a ZeroMQ consumer endpoint and feeds them into an Ignite cache. • RocketMQ - Ignite RocketMQ Streamer consumes messages from an Apache RocketMQ consumer endpoint and feeds them into an Ignite cache. 4 Apache Ignite Extensions • Storm - Ignite Storm Streamer consumes messages from an Apache Storm consumer endpoint and feeds them into an Ignite cache. • MQTT - Ignite MQTT Streamer consumes messages from a MQTT topic and feeds transformed key-value pairs into an Ignite cache. • Camel - Ignite Camel streamer consumes messages from an Apache Camel consumer endpoint and feeds them into an Ignite cache. • JMS - Ignite JMS Data Streamer consumes messages from JMS brokers and inserts them into Ignite caches. • Kafka - Apache Ignite Kafka Streamer module provides streaming from Kafka to Ignite cache. 5 The release dependencies Ignite Extensions modules 6 The release process Ignite Extensions modules 7 Apache Ignite Extensions release process Ignite Extensions modules 8 Migration Guidelines • An extension can be released separately from Apache Ignite core. • An extension has to be tested with existing testing tools like TeamCity and Travis. • Each extension is validated against every Apache Ignite core release and a new version of extension to be released along with Apache Ignite code if changes are required. • Extensions can continue to have their own specific version release and need not aligned with Apache Ignite core release version. 9 Migration Risks • Modification of existing build pipeline and testing procedures. • Release policies have to be updated to ensure that modules & core versions compatibility matrix is updated regularly 10 Migration Benefits • Faster release cycles for Apache Ignite Extensions. • Less overhead for Release Manager when planning Apache Ignite releases. • Individual extension module can be released independently. • Less scope for validation and quick testing cycles for releases. 11 New Apache Ignite Extensions • Pub-Sub - Pub/Sub module is a streaming connector to inject Pub/Sub data into Ignite cache. • Spring Boot Autoconfigure - Apache Ignite Spring Boot Autoconfigure module provides autoconfiguration capabilities for Spring-boot based applications. • Spring Boot Thin Client Autoconfigure - Apache Ignite Client Spring Boot Autoconfigure module provides autoconfiguration capabilities for Spring-boot based applications. 12 Apache Ignite Extensions - Upgrade Current Maven - POM New Maven - POM <dependency> <dependency> <groupId>org.apache.ignite</groupId> <groupId>org.apache.ignite</groupId> <artifactId>ignite-flink</artifactId> <artifactId>ignite-flink-ext</artifactId> <version>2.8.1</version> <version>1.0.0</version> </dependency> </dependency> 13 Data loading and Streaming • Data streamers publish continuous stream of unbounded set of data into Ignite Nodes Ignite Cluster Ignite Streamers Ignite clients • Data get partitioned and distributed evenly between Ignite nodes. • Streamed data can be processed in parallel. Apache Flink • Ignite clients can also perform concurrent SQL queries in data. 14 More Info • https://cwiki.apache.org/confluence/display/IGNITE/IEP-36:+Modularization 15 Q & A.

  • Beyond Relational Databases
    EXPERT ANALYSIS BY MARCOS ALBE, SUPPORT ENGINEER, PERCONA Beyond Relational Databases: A Focus on Redis, MongoDB, and ClickHouse Many of us use and love relational databases… until we try and use them for purposes which aren’t their strong point. Queues, caches, catalogs, unstructured data, counters, and many other use cases, can be solved with relational databases, but are better served by alternative options. In this expert analysis, we examine the goals, pros and cons, and the good and bad use cases of the most popular alternatives on the market, and look into some modern open source implementations. Beyond Relational Databases Developers frequently choose the backend store for the applications they produce. Amidst dozens of options, buzzwords, industry preferences, and vendor offers, it’s not always easy to make the right choice… Even with a map! !# O# d# "# a# `# @R*7-# @94FA6)6 =F(*I-76#A4+)74/*2(:# ( JA$:+49>)# &-)6+16F-# (M#@E61>-#W6e6# &6EH#;)7-6<+# &6EH# J(7)(:X(78+# !"#$%&'( S-76I6)6#'4+)-:-7# A((E-N# ##@E61>-#;E678# ;)762(# .01.%2%+'.('.$%,3( @E61>-#;(F7# D((9F-#=F(*I## =(:c*-:)U@E61>-#W6e6# @F2+16F-# G*/(F-# @Q;# $%&## @R*7-## A6)6S(77-:)U@E61>-#@E-N# K4E-F4:-A%# A6)6E7(1# %49$:+49>)+# @E61>-#'*1-:-# @E61>-#;6<R6# L&H# A6)6#'68-# $%&#@:6F521+#M(7#@E61>-#;E678# .761F-#;)7-6<#LNEF(7-7# S-76I6)6#=F(*I# A6)6/7418+# @ !"#$%&'( ;H=JO# ;(\X67-#@D# M(7#J6I((E# .761F-#%49#A6)6#=F(*I# @ )*&+',"-.%/( S$%=.#;)7-6<%6+-# =F(*I-76# LF6+21+-671># ;G';)7-6<# LF6+21#[(*:I# @E61>-#;"# @E61>-#;)(7<# H618+E61-# *&'+,"#$%&'$#( .761F-#%49#A6)6#@EEF46:1-#

  • Thesis Artificial Intelligence Method Call Argument Completion Using
    Method Call Argument Completion using Deep Neural Regression Terry van Walen [email protected] August 24, 2018, 40 pages Academic supervisors: dr. C.U. Grelck & dr. M.W. van Someren Host organisation: Info Support B.V., http://infosupport.com Host supervisor: W. Meints Universiteit van Amsterdam Faculteit der Natuurwetenschappen, Wiskunde en Informatica Master Software Engineering http://www.software-engineering-amsterdam.nl Abstract Code completion is extensively used in IDE's. While there has been extensive research into the field of code completion, we identify an unexplored gap. In this thesis we investigate the automatic rec- ommendation of a basic variable to an argument of a method call. We define the set of candidates to recommend as all visible type-compatible variables. To determine which candidate should be recom- mended, we first investigate how code prior to a method call argument can influence a completion. We then identify 45 code features and train a deep neural network to determine how these code features influence the candidate`s likelihood of being the correct argument. After sorting the candidates based on this likelihood value, we recommend the most likely candidate. We compare our approach to the state-of-the-art, a rule-based algorithm implemented in the Parc tool created by Asaduzzaman et al. [ARMS15]. The comparison shows that we outperform Parc, in the percentage of correct recommendations, in 88.7% of tested open source projects. On average our approach recommends 84.9% of arguments correctly while Parc recommends 81.3% correctly. i ii Contents Abstract i 1 Introduction 1 1.1 Previous work........................................

As an alternative to traditional relational DBMS 2. Overview distributed, in-memory DBMS are proposed. In this paper, we investigate capabilities of Apache Ignite and VoltDB from the This chapter discusses the features of Apache Ignite and point of view of relational operations and compare them to VoltDB.
